Tramway
On tramways, an open coach is a six- or eight-wheeled driving car or trailer, which has an especially high volumetric capacity. Unlike the earlier, typical platform coaches, open coaches do not have partitions with doors between the entrance area and the actual passenger compartment. These coaches were popular in central Europe in the early 1950s and replaced the old (mainly four-wheeled) platform coaches. Whilst in West Germany, Austria and Switzerland this type of vehicle was rapidly replaced by articulated trams, in East Germany, the Tatra trams were the norm during the 1960s in many cities. The same was true in the former Eastern Bloc countries.
